To all zn/wm t may concern:

Be it known that I, HARRY P. I-IoMERs, al citizen of the UnitedStates,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement inIVindow-Sashes; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the characters ofreference marked thereon, to be a full, clear, and exact description ofthe same.

This invention relates to an improvement in window sashes andparticularly to sashes which are hung from the bottom rail and which areadapted to tilt forward to provide for ventilation and to permit thesash to be reversed in position. l/Vhat are known as bottom-hung sasheshave been employed and adapted to swing forward at their upper ends toprovide for ventilation, but some stop or device is necessary to arrestsaid forward movement of the upper edge of the sash to prevent danger ofbreaking by the falling of the sash. Means have been provided to limitthe forward movement of the sashes and the obj ect of this invention isto provide means for arresting the forward movement of the sash and yetpermitting it to be turned when required, and the invention consists inthe construction and arrangement of parts as will be hereinafterdescribed and particularly recited in the claims.

Reference is made to the accompanying drawings representing in-- Figure1 a front view of a window provided with a sash hung in accordance witmy invention;

Fig. 2 a sectional view on the line 2-2 of Fig. l, enlarged;

Fig. 3 a similar view with the upper edge of the lower sash movedforward;

Fig. i a sectional view on the line 4-4 of Fig. 1;

Fig. 5 a perspective view of the locking lever detached;

Fig. 6 a perspective view of the stop plate detached;

Fig. 7 a broken sectional detail view illustrating the pin to limit themovement of the stop lever.

In carrying out my invention I employ the usual sash consistingof thelower rail 10, the upper rail 11, and side rails 12 and 13. Secured tothe side rails near their lower ends are chains or cords le which areconnected with the usual window weights for balancing the sash. Thissash is adapted to be moved vertically in the usual guideways and heldin place by stops 16 and 17, which are hinged at their forward edges tothe window casing 18 so that they may be turned outward to giveclearance to the lower sash. To prevent the upper edge of the sash frommoving forward farther than desired I provide the edge with a plate 19formed with a series of projecting stops 20, 21 and 22, more or less innumber. These stops are adapted to be engaged by a lug 23 formed at thelower end of a lever 24- pivotally mounted on a plate 25 secured in thewindow 'casing above the upper sash rail 11 when that is in itslowermost position.` At the upper forward corner of the plate 25 is ahole 26 through which a pin 27 extends, this pin being projected outwardby a spring 28 located in a socket 29 formed in the window casing 18.'Io separate the meeting rails of the sashes to provide for ventilation,the stops 16 and 17 will be opened and as the sash is hung from thebottom the upper part will tend to drop forward, and as it moves forwardit is caught by the engagement of the lug 23 with the stop 20. IffurtherV movement is required, the lever 24: is swung outward so thatthe lug 23 may engage with the stops 21 or 22, beyond which the lever 24cannot be moved, as it will engage with the pin 27. TWhen, however, thewindow washer desires to reverse the sash, it is only necessary to pushthe pin 27 inward, allowing the lever 24 to be entirely disengaged fromthe sash, which is then free to be reversed end for end. To prevent thelever 24 from engaging with the stop plate as the sash is moved up ordown, I provide a stud 81 which limits the inward-swinging movement ofthe lever 24. I thus provide a simple and convenient means for holding awindow sash in a partly open position and provide means to prevent itsaccidental opening adapted to engage with the stops on the said sftopplate or be entirely disengaged thererom.

2. The combination with e bottom-hung` window sash of a. stop platesecured at thev upper end of oneside thereof7 said stop plate formedwith e series of stops, a plate secured to the window casing, e leverpivotally connected with said plete7 provided at its lower end with alug adapted to engage with the stops on the said stop plate, seid leverpla-te also formed with an opening at its forward upper end, and aspringVpin projecting outward through seid opening.

In testimony whereof, I have signed this speeilioation in the presenceof two subscrib- Aing witnesses.
